HESI Fundamentals Practice Questions
1. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 400 mL/hr
- B. 200 mL/hr
- C. 300 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.
2. A client has been tentatively diagnosed with Graves' disease (hyperthyroidism). Which of these findings noted on the initial nursing assessment requires quick intervention by the nurse?
- A. A report of 10 pounds weight loss in the last month
- B. A comment by the client 'I just can't sit still.'
- C. The appearance of eyeballs that appear to 'pop' out of the client's eye sockets
- D. A report of the sudden onset of irritability in the past 2 weeks
Correct answer: C
Rationale: The appearance of eyeballs that appear to 'pop' out of the client's eye sockets, known as exophthalmos, requires quick intervention as it is a severe symptom of Graves' disease. Exophthalmos can indicate an acute condition and may lead to serious complications such as optic nerve damage or corneal ulceration. Weight loss, restlessness, and irritability are common manifestations of hyperthyroidism but do not pose immediate risks compared to the ocular complications associated with exophthalmos.
3. By the second postoperative day, a client has not achieved satisfactory pain relief. Based on this evaluation, which of the following actions should the nurse take, according to the nursing process?
- A. Reassess the client to determine the reasons for inadequate pain relief.
- B. Wait to see whether the pain lessens during the next 24 hours.
- C. Change the plan of care to provide different pain relief interventions.
- D. Teach the client about the plan of care for managing pain.
Correct answer: A
Rationale: Reassessing the client is crucial to identify the reasons for inadequate pain relief. This action allows the nurse to gather more information, evaluate the current pain management interventions, and make necessary adjustments to the care plan. Waiting for the pain to lessen without taking action delays appropriate pain management. Changing the plan of care without reassessment may lead to ineffective interventions. Teaching the client about the plan of care should be based on a reassessment of the current pain relief status to ensure tailored and effective pain management strategies.
4. A nurse is calculating a client's fluid intake over the past 8 hr. Which of the following items should the nurse plan to document on the client's intake and output record as 120 mL of fluid?
- A. 2 cups of soup
- B. 1 quart of water
- C. 8 oz of ice chips
- D. 6 oz of tea
Correct answer: C
Rationale: The correct answer is C: 8 oz of ice chips. When calculating fluid intake, the nurse should document half of the volume of ice chips to account for the air in between the chips. Therefore, 8 oz of ice chips equals 120 mL of fluid. Choices A, B, and D are incorrect because they do not equate to 120 mL of fluid intake as per the given scenario. Choice A, 2 cups of soup, is more than 120 mL. Choice B, 1 quart of water, is significantly more than 120 mL. Choice D, 6 oz of tea, is less than 120 mL.
5. What is the rate of delivery in mL/hr if a total volume of 750 mL is infused over a period of 7 hours?
- A. 107 mL/hr.
- B. 107 mL/hr.
- C. 107 mL/hr.
- D. 107 mL/hr.
Correct answer: A
Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.
